Abstract
A method and apparatus for the generation of power and for the generation of higher temperature heat, by using a work process with isentropic compression of a gaseous working fluid, and the expansion of the working fluid with heat addition and expansion adiabatically. Work is supplied to the working fluid during compression and work is extracted during expansion from the working fluid; the difference is the work output for the system. Heat is added into the working fluid during the expansion, and such heat addition may be in steps with compression between such steps. Heat is removed from the working fluid at a higher pressure than the heat addition, with the heat removal at constant pressure normally. Working fluids include air, nitrogen and oxygen.
Claims6
A method of generating power comprising:
- a. compressing a compressible working fluid isentropically in an approximately non-flow process;
- b. removing heat from said working fluid after the compression;
- c. expanding said working fluid with heat addition and generation of power.
In a power generator wherein within a rotating rotor a compressible working fluid is compressed and then expanded, the improvement comprising:
- a. compressing said working fluid adiabatically by centrifugal force in an outwardly extending fluid passage within said rotor;
- b. removing heat from said working fluid downstream of said compression in a heat exchanger carried by said rotor;
- c. expanding said working fluid in an inwardly extending fluid passage with heat being added into said working fluid during the expansion by a heat exchanger being carried by said rotor.
